Pozdrav svima,
interesuje me da li gore navedeni ruter moze da se natera da mu se preko ISDN interfejsa pristupi sa neke remote lokacije preko jednog od podrzanih PPP protokola. Sam ruter se na poziv javlja ali ne odgovara u klasicnom obliku kako kad se standardno konektuje na internet, vec se posle 20-ak sekundi diskonektuje. IOS je C870 Software (C870-ADVENTERPRISEK9-M), Version 12.4(6)T, RELEASE SOFTWARE (fc1). Da ne bude zabune. ADSL sljaka odlicno ali me ovo buni - tj. interesuje da li uopste i moze da se izvede. Deo startap konfe je dole kao i deb ppp.

Moze.

"Cisco 876 and Cisco 878 routers can use the ISDN S/T port for remote management. With an advanced enterprise (c870-adventerprisek9-mz) image, a Cisco 876 router can also use the ISDN S/T port for dial backup. "

http://www.cisco.com/univercd/...eng/pt3/dialbkup.htm#wp1015457

na istom linku imas i primere konfiguracije. Ono sto mislim da je sigurno greska je da moras imati definisan isti tip autentifikacije i na Dialer i na fizickom interfejsu (ppp authentication chap callin).

Evo i jednog dobrog teksta o CHAP-u http://www.cisco.com/warp/public/471/understanding_ppp_chap.html

Poz,
Milenko.

Zapravo, na fizickom interfejsu mu ne treba ništa od PPP konfiguracije. Sve treba da konfiguriše na samom Dialer interfejsu - gde ništa od toga nije definisano.

Pozdrav svima i hvala na brzim odgovorima. Radi lakseg detektovanja problema, konfa je promenjena u PAP , ali ruter opet ne odgovara i staje na istom mestu...

Pročitaj moju poruku još jednom... Treba da primeniš authentikaciju na Dialer, a ne na BRI interfejsu. Dialer interfejs je taj koji radi PPP, ne BRI.
[ Ijahman @ 25.05.2007. 15:07 ] @
Jedino sto sam mogao jos da dodam pametno je ovo

Code:

Cisco_876(config#int dia11
Cisco_876(config-if)#ppp authentication pap callin default

ali i dalje isto :(
